This invention relates to hair clasps and I methods of producing the same. More par ticularly it relates to an ornamental hair clasp provided with a bar ;or other ornainental'element of Celluloid or other hardened' plastic material which isfrigidly attached to a hairpin in order to give it a Q In its preferred I I clasp consists of a wlrehair pin having two pleasingappearance, and to afsimple, efficient andeconomical method of'producing the article.

The preferred methodof forming my hair clasp is as'follows: Celluloid stock in any desirable shape may be employed although I prefer to use a. small round barof celluloid. This is cut into suitable lengths and a slot or groove 14 is cut by means of a saw or other suitable tool, preferablyfsubstan- 7 may be molded with the groove in it. The

by. I The solvent used may be anyfof, the. usual solvents of celluloid butIprefer to use acetic acid. I have found that a 99 per solvent to be -;e mploy.ed.1 The celluloid-is preferably allowed to: remain JilltllG acetic acid about one minute. r

After being dipped, the hair clasp, is dried hair clasps'on a conveyor which conveys the articles through aheated room or ove'nj I- have found that. an average temperature for the drying, finishingand'hardening operation. At this temperature it has been I found that the drying, finishing and hard-f l 90 one minute so that thereafterthe hair pins 7 may be handled without danger of marring the surface of thecellu'loid'or separating ening will-be completed in approximately the celluloid member-and hairpin.

It also will be apparent that I may em; ploy diflerent'colored celluloid or other hard-1 100 ened plastic ornamental elements and that;

Having described my invention, I claim:

' 1. A hairv clasp of the character described comprising a wiremember formed of two legs and an ornamental element of hardened plastic material havinga groove in one side extending substantially throughout its length and having one leg of the wire member attached -to said ornamental i element throughout substantially the Whole length of said groove.

2. The method of producing ahair clasp comprising forming a grooved elementof hardened plastic-material, inserting a wlre 3. The method-ofproducing a-hair clasp comprising formingv a grooved celluloid member, inserting awire member into said groove, dippingsaid attached celluloid and wire members into an acid to soften said celluloid and indurating said celluloid ;memher by subjection to heat.

i. The method of producing a 'hair clasp comprising forming agrooved celluloid member, inserting a wire memberinto said groove, dipping said attached celluloid and wire members-into acetic acid'to soften said celluloid and induratingthe celluloid memher by subjectionto heat. I v

5. A method of producing a hairrclasp comprising forming a grooved celluloid member, inserting a wire member intosaid groove, dipping said attached celluloid) and wiremembers into.a bath.- of 99 percen pure aceticacid to softenisaid celluloidand indurating said celluloid member by subjection to heat.
